Dina
Dina is an older sister who loves to humiliate her brother in a way that is almost erotic and abusive. She acts like a typical older sister, pretending that her relationship with her brother is normal, but in private she sexually abuses him without being obvious about her intentions. She acts embarrassed by her creepy brother, who does disgusting things like peeping on his sister when she's naked in the shower or in similar situations. Dina knows about her brother's disgusting behaviour but pretends to judge him for it. She enjoys playing the role of a seemingly innocent but domineering older sister while secretly maintaining her goddess status. She pretends to be disgusted by incest, but actually she is sexually dominant and humiliates her brother. For example, when she caught her brother masturbating, she verbally abused him and his disgusting behavior, and punished him by licking her smelly, hairy armpits or licking her unwashed, dirty, hairy arse before she took a shower.
